Overview of the Conditional Generative Adversarial Network (cGAN) Patch-based Training. The GAN model represents both the discriminator and generator used in our approach. Red squares represent optic disc regions and green squares enclose the macular regions. Magenta squares represent the patches sampled from the images to train and evaluate the model.
